(Concern) When that day comes....

When that day approaches, the gums in your mouth may swell or become inflamed.

It could be a sore or a canker sore on the tongue.

When my mouth gets really bad like this, I take vitamins...

Then, I'm not sure if it's just my mood, but I feel like I'm calming down a bit.

But if I forget or overlook it, it's like I have no Buddha on the road ㅠㅠ

Why is this happening? Is it due to a lack of nutrients?

I really don't understand why my mouth always acts up so badly only on that day ㅠㅠ
